My thoughts: I was confused by the GTHD showing, since it was only GT4 upconverted and didn't look much advanced over GT4 as a result, I don't know why it was shown. Interestingly if I recall correctly, that was the only game where they specified the resolution and framerate, although I may have missed something. Heavenly Sword looked nice, as well as a Yu-gi-oh style card game using the Eyetoy to bring CG into real life. There was a 99 Nights-style game, Genji, that looked pretty average, but the shooter 8 Days was stunning, we will have to see how that compares to the new Hard Boiled-based game coming out. Most of the other stuff was ok, some impressive, some disappointing, but I'll wait until we see high definition direct feed trailers posted on Playsyde to say more.
Overall however I felt good about the PS3 and the games it has coming out, if not blown away just yet. The price point is about where I expected as well, we'll have to see what the launch titles are before I decide to buy.
Now we can wait to see if we get a price on Microsoft's HD DVD drive tomorrow and how their games look compared to the playable PS3 games shown.
